Installation
Measures after long-term storage
Replace ball bearings and radial shaft seal
!
When the length of storage until assembly is exceeded by
4 years
for the
storage conditions provided in Storage [
➙
20].
1. Replace the rolling bearing.
2. Clean adjacent bearing areas for open ball bearings and re-grease.
3. Replace and grease the radial shaft seal.
If the bearing conditions vary (Storage [
➙
20]), a reduced ball bearing service life
is to be expected.
Measuring the motor insulation resistance
Measure the insulation resistance of the motor at 500V DC voltage between
the conductors of the main circuit and protective conductive system.
Value ≥1 MΩ: no measures necessary.
Value <1 MΩ: Dry winding.
Mounting conditions
For safe operation, comply with the following installation conditions
▪
Always secure the G-BH1 | G-BH9 to an even (
± 0.5 mm
[0.197]) assembly
surface or base frame using screws. The dimensions and load-bearing capaci-
ty must be designed for the G-BH1 | G-BH9.
▪
When installing outdoors, take protective measures against the effects of
weather.
▪
When installing in enclosed spaces, ensure that there is sufficient ventilation.
For conveyed media other than air, leaks from the G-BH1 | G-BH9 must be
taken into account (e.g. forced ventilation, gas monitoring).
▪
No exhaust air from other machines in the suction area of the motor fan.
▪
External oscillations, abrupt loads and accelerations are not permitted.
▪
External mechanical loads are not permitted on the G-BH1 | G-BH9 and its at-
tachments (e.g. piping without a support, climbing the G-BH1 | G-BH9 and its
attachments).
▪
If there is a risk of condensation forming in the interior of the G-BH1 | G-BH9,
take protective measures (e.g. heating, moisture separators).
Reduction of oscillations and noises
Noise emissions and vibrations can be reduced by the following measures.
▪
Do not set up the G-BH1 | G-BH9 in set-up areas that conduct or radiate
sound.
▪
Equip installation surfaces with intermediate layers of noise damping material.
▪
Use additional silencer (item 5230, [
➙
15]).
▪
When mounting horizontally, use spring elements on the foot (item 5210, [
➙
15]).
▪
It is recommended to flexibly set up the G-BH1 | G-BH9 on springs elements.
